Figure 1.8. An example of the synthesis of new tetrasubstituted Pcs [8]. Chemical Modification Of Phthalocyanines And Their Application In Section A-Research paper The Synthesis Of Phthalocyanine Pigments Eur. Chem. Bull. 2022,11(11), 145 – 151 151 The chemistry of sandwich compounds based on phthalocyanine complexes with rare earth elements is actively developing. The ability of supramolecular complexes of this type to reversible oxidative-reducing transformations determines the prospects for their use as components of electrochromic systems, sensory and conductive materials [7]. Two- and three-deck compounds were obtained (Figure 1.8) with a wide range of ions (lanthanides, actinoids, some elements of the main groups) and with the variation of peripheral substituents in the macroligand, including Pcs complexes with crown-5 fragments [7-9]. Figure 1.9. Examples of the structures of sandwich Pcs complexes. CONCLUSIONS The synthesis of homoleptic (with the same ligands) sandwich complexes is usually carried out either similarly to the production of MPc (Figures 1.1, 1.7), but in the presence of ions capable of octacoordination, or by the interaction of these ions with Li2Pc (H2Pc) in a high-boiling solvent. Mixed condensation of phthalogens, mixed complexation in solution, or tetramerization of phthalogens of a new ligand in the presence of an existing complex is used to obtain heteroleptic (with different ligands) compounds [8].
